[Chiuso] Can't find a button and text (in a tab) in string translations or advanced editor

Background of the issue:
I have translated the one-page site from French to English using WPML. I have enabled the localisations, etc.

Symptoms:
There are some buttons and texts in a tab that don't appear in string translations or in the advanced page editor. Specifically, the texts in the 'OUR SERVICES' section tabs and the buttons in the 'TEAM' section remain in French when they should be in English 'READ MORE'.

Questions:
Why don't the texts in the 'OUR SERVICES' section tabs appear in string translations or the advanced editor?
Why do the buttons in the 'TEAM' section remain in French instead of English 'READ MORE'?
